update_delete.php
Contains javascript and HTML code update button with class "update_button" and textarea with id "content". When a user click update button the new message is display to top of the ol timeline list with an id "update" with an animated slide Down effect with jQuery and Ajax.

If you want fadeIn and fadeOut effect just replace the word "slideDown" to "fadeIn" and "slideUp" to "fadeOut" in this following script.

i'm making wall post like facebook, n it can delete comments or status, when i click the delete button, the comments/status was deleted, but the page like refresh, so the animation slide up can't see by user. how to make it stay at this comments/status..?? please anyone help me....it's important..thx

I posted earlier today but I don't see my comment. I have used your script and have got everything running BUT for some reason when I refresh the page and then come back to the comments, they are gone. I looked into mysql and they are inserted just fine, however they don't show as older post. Everything else works great! I'm super excited about this comment system and would really appreciate anyones answer or help on the matter.

It'd be great if you can comment on main ajax code lines, explaining what you're doing, so this would be really a tutorial. The code is a very nice approach thou. I'd only suggest to include the way you display the old updates, so you can see them when you visit the page.

Thanks Bro for sharing this wonderful script. I added to my collection.

The only problem i have with it is, takes longer to load data from array so i decided to pull all my data from db then put all fetched data serialised in a text file and the call text file $_sessionID.txt dynamically at run time, it changes for each user of my website then gets deleted after logout. still it is slow as it was reading form array. Any suggestion how to improve the loading time?
